Combustion and Ventilation Air Indoor Units The boiler must be supplied with sufficient quantities of non-contaminated air to support proper combustion and equipment ventilation. Combustion air can be sup- plied via conventional venting, where combustion air is drawn from the area immediately surrounding the boil- er, or via direct vent, where combustion air is drawn directly from outside. All installations must comply with the requirements of NFGC for U.S., CSA B149 for Canada, and all local co
